Yeah, let us know what version of energy you are running and possibly post a screenshot of your home screen.
If you are using sense or manila you have a rom of icons at the bottom of your home screen and one of those is for email and another one is for sms/mms so you click on the one you want. You can navigate to one or the other using the account picker screen after you click on one of those tabs but I don't understand why you would click on the email tab and navigate to sms instead of just clicking on the sms tab.
If you are running Titainium then you won't have a row of icons at the bottom of your homescreen you will just have text in a row on the left side of your homescreen(today screen.)
